Chelsea suffered a serious setback, losing 2-0 to Swansea in last nightÔÇÖs semi-final first leg, leaving them with tough task at the Liberty Stadium in two weeks time.
But Cahill remains upbeat in the knowledge that Chelsea have overcome the odds before, most notably in last year’s Champions League final, when they defeated Bayern Munich at the German sideÔÇÖs own ground.
On the way to this famous victory, Chelsea were beaten 3-1 in the last 16 by Napoli but managed to pull off a 4-1 victory in the return leg at Stamford Bridge.
Chelsea went on to beat Barcelona in the semi-finals, and win the final at the Allianz Arena on penalties.
“It is never over,” Cahill told the┬áLondon Evening Standard. “We created enough chances to go in at half-time maybe three or 4-0 up – if we take those chances in the away leg and keep it tight, weÔÇÖll win.
